Disk partitions are a way to divide a physical hard disk into smaller, 
independent pieces that can be managed separately.  In a nutshell ...

. you can have up to 4 primary partitions on a physical disk
. if you need more than 4, you can designate one of those 4 partitions 
as an extended partition, and then further sub-divide that extended 
partition into many logical partitions.

Windows is installed into a primary partition.  Once installed, Windows 
can use other partitions as data space.  A drive letter is associated 
with each partition that Windows is using.

Linux can be installed into either primary or logical partitions.  Once 
installed, Linux can use other partitions as data space also.  Drive 
letters are not used; rather, a partition is associated with a directory 
  through the mount(8) command.  For example, you can mount the 
/dev/hda3 partition to the /mnt/a3 directory.

Red Hat has on-line manuals that you might look at ...
www.redhat.com ->
Documentation ->
Red Hat Enterprise Linux ->
System Administration Guide ->
Managing Disk Storage ->
Standard Partitions using parted ... is one example of a manual section 
that you might find useful.
